<p>A limiting differential amplifier circuit comprises first and second controllable current sources (I1, I2) fed with the differential input signal (V@) and a controllable differential load circuit (IL1, IL2) and a feedback element ( beta ), the feedback element comprising transistors (T1 T2) sensing the common mode output voltage and a diode (D1) for translating the current generated into a control voltage (Vc) to control the differential load circuit whereby to provide high-voltage gain in the differential signal mode and low common-mode gain.</p> |
